python decorating an object with @

I want to achieve the decorator design pattern in python using the @ syntax, my code:

class Sandwich():
    height = 5
    width = 8

    def ingredients(self):
        print("I have bread")
    
class Cheese_decorator():
    def __init__(self,obj):
        self.obj = obj
        #something else here so the object becomes the same as the passed one except for the methods to decorate below

    #decorated method
    def ingredients(self):
        self.obj.ingredients()
        print("I also have cheese")
     
    #any other method to decorate here

sandwich = Sandwich() # this sandwich wont be decorated
cheese_sandwich = Cheese_decorator(Sandwich()) # this sandwich is decorated

sandwich.ingredients() # prints I have bread
cheese_sandwich.ingredients() # prints I have bread I also have cheese

is there anything I can do like:

sandwich = Sandwich()
cheese_sandwich = @Cheese_decorator
                  sandwich

? I want to have the decorated object as a var
